. METALLIC SEAL.

SPECIFICATION forming part of Letters Patent No. 260,279, dated June 27,1882.

Application filed February 25, 1882.

To all whom it may concern.: Y

Be it known that I, EDWARD J BROOKS, a citizen of the United States,residing at East Orange, in the State of New Jersey, have invented a newand useful Improvement in Metallic Seals, of which the following is aspecification.

This invention relates to the construction of lead-and-tin seals forsecuring the doors of railway freight-cars, and for like uses, and thatform of said seals in which a leaden rivet unites the ends of a flexiblestrip (of uniform width) which is adapted to be cutfrom the ordinarytin-plate of commerce and punched with the requisite rivetholes, andalso to be readily stamped or printed with lettering or distinguishingmarks, if these be desired, so as to be cheaply produced. Heretoforecast rivets for such seals have constituted a distinct article ofmanufacture, and the necessarily somewhat slow work of inserting theirstems in the rivetholes of the respective ends of the strips preliminaryto pressing as a part of the sealingv operation, the inconvenience ofcarrying the parts of the seals separately, and the difficulty of ndingthe outside of stamped or lettered sealing-strips under somecircumstances, have materially detracted from the value of such seals.In my specification, forming part of Letters Patent No. 246,068, datedAugust 23, 1881, I describe a lead-and-tin seal of another form, havingits parts united permanently inV the process of manufacture, and setforth the advantages of this mode of making seals.

My presentl invention consists, first, in an improved lead-and-tin sealcomposed of a rivet and sealing-strip possessing the advantageousqualities aforesaid, with the rivet cast on or permanently fastened toone end of the strip, so as to free this superior form of seal from thesaid disadvantages without materially increasing its first cost.

Figure 1 of the accompanying drawings is a perspective View of one of myimproved seals as furnished for use. Fig. 2 represents a longitudinalsection of the Same ready for pressing. Fig. 3 represents across-section on the line 3 3,Fig. 2. Fig. 4 represents a back view, andFig. 5 a fragmentary* front view, of the same pressed. Fig. 6 is aperspective view of (No model.)

| the sealing-strip as it appears before providing it with the rivet;and Fig. 7 represents a vertical longitudinal section of a series ofmolds, illustrating the proposed method of casting the rivets on thestrips, like letters of reference indicating corresponding parts in theseveral figures.v

My improved seal consists (unpressed) of a tin strip, S, and a rivet, R,of lead or an equivalent soft metal, permanently united, as representedby Figs. 1 to 3, inclusive. Said tin strip S may be, and by preferenceis, of the customary narrow form and of uniform Width, havingrivet-holes c b in its respective ends. I propose making it either withor without an index-hole, c, or an equivalent thereof, at one end, andlettering or distinguishing marks, d, Fig. 6, on the face of the strip.The rivet B, by preference cast on the strip end, with which it is fast,permanently occupies and fills the said rivet-hole a by means of itsstem e,which protrudes beyond the strip the proper distance to extendthrough the other rivet-hole, b, so as to temporarily unite the ends ofthe strip preparatory to pressing, as shown in Figs. 2 and 3, and to beheaded down, so as to securely unite the strip ends in its pressedcondition, as shown in Figs. 4 and 5. y

The rivet-head is preferably of greater diameter than the width of thestrip, so as to embrace its edges for solidit-y of attachment, and atthe same time to form cheeks f f flush with the back of the strip, asshown in Figs. 1 and'3, which will ordinarily become united with thestem e by a lm of lead, more securely uniting the parts in the processof manufacture, and in the pressing operation will unite with the headof the pressed stem, as indicated in Fig. 4. The rivet may however be ofany preferred size and shape, and may be stamped with distinguishingmarks, g h, Figs. 4 and 5, of any description, on either or both faces;or may be pressed plain for some uses, and particularly if the strip beprovided with lettering or dis` tinguishing marks d, as aforesaid.

The strip S is manufactured in customary manner, but preferably with itsrivet-hole a smaller than the hole b, and with the indexhole c, or anequivalent thereof, to indicate the 9S In producing this seal I proceedas follows:

latter. This may all be done, together with the stamping or printing ofthe lettering or distinguishing-marks d, if these be desired, in thesheet, before cutting the latter into strips. Molds l 2 3, Fig. 7, forthe rivets It, are constructed with a transverse indentation, t, in thetop of the lower part of each mold, to receive the strip end upon whichthe rivet is to be fast. This strip end is inserted, as shown at 2, Fig.7, with the -rivethele a in line with the in gate of the mold. The leadis then poured, filling the head portion through said rivet-hole a, andforming the stem of the rivet in an extension of the ingate, as shown at3, Fig. 7. Alarge numberof rivets Will be simultaneously cast, as inordinary molds, and thc improved seals can thus be very readily andcheaply manufactured.

I do not claim, broadly, a seal having a sheetA metal shackle and asoft-metal rivet united in zo the act of casting the latter, as I amaware that this has before been proposed. Neither do I claim herein themethod of cast-ing the rivets above specified 5 bntI reserve the rightto claim this in another application for patent to be tiled 2 5hereafter.

I claim as new- A tin-and-lead seal composed of a striphavingrivet-holes in its respective ends and a rivet fast thereon havinga stem which tightly lls 3o one of said rivet-holes and is looselyfitted to the other, substantially as herein specified.
